[Ssh-sftp-perl-users] Net::SSH::Perl issue

[Ivaylo T. <iva...@gm...>]

Hi,

I am using following code to configure Juniper router:

  my $ssh = Net::SSH::Perl->new($ip, protocol => 2);
  $ssh->login($user, $pass);
  foreach (@commands)
    {
      my($out, $err, $exit) = $ssh->cmd($_);
    }

but seems that every command in @commands is transmitted in a separate
channel than the previous despite that the protocol is SSH2.
With first command I am in configuration mode (look at Log file bellow)),
but the next command is executed in non-configuration mode on next channel.
What can I do to send all commands in one single channel ?
